Hi,
I recently got StoragaTek 2500 and I would like to connect it to my solaris machine, since I don't have much experience with storages, could someone point me how to do so, how can i present disks from storage on my solaris os? (everything is already connected)
thanks in advance (1 Reply)
Hi Guys and Gals,
Wionder if you could help me, got a problem with a controller on a storagetek 2540, dead when fully powered up but if you reboot, it is ok for a couple of seconds (and you can ping it). Then once the array is fully up, it goes faulty and is un-pingable.
Had anyone... (4 Replies)

Hi peeps,
Was wondering if anyone can help me, got a couple of storagetek 2540's that I need to configure. Trouble is I think they were brought as second user as all that came with them was cables.
Does anyone know how to configure them (i.e. create raid sets and map to Luns and present... (1 Reply)
Hi,
I have recently purchase a SUN Storage Tek desktop LTO 4 HH tape drive and connected to a IBM AIX 5.1 server.
The server can detect the tape device.
Can someone please advice urgently.

We're moving our production 3510FC to development, so we need to replace the production 3510FC. The 6140 is nice, but pricey.
Here's the question: Would two 2540's (RAID 10) be 'faster' than one 3510? (RAID 10) and faster than one 6140 (RAID 10)?
One StoregeTek 6140 (16x72GB 15k rpm fc-al... (12 Replies)
MTIO(4) Kernel Interfaces Manual MTIO(4)NAME
mtio - magnetic tape commands
SYNOPSIS
#include <sys/types.h>
#include <sys/mtio.h>
#include <sys/ioctl.h>
DESCRIPTION
The magnetic tape devices described in sd(4) may be sent commands or queried for their status using the following ioctl calls:
ioctl(fd, MTIOCTOP, &struct mtop)
ioctl(fd, MTIOCGET, &struct mtget)
The struct mtop, struct mtget and associated definitions are defined in <sys/mtio.h> as follows:
/* Tape operations: ioctl(fd, MTIOCTOP, &struct mtop) */
struct mtop {
short mt_op; /* Operation (MTWEOF, etc.) */
int mt_count; /* Repeat count. */
};
#define MTWEOF 0 /* Write End-Of-File Marker */
#define MTFSF 1 /* Forward Space File mark */
#define MTBSF 2 /* Backward Space File mark */
#define MTFSR 3 /* Forward Space Record */
#define MTBSR 4 /* Backward Space Record */
#define MTREW 5 /* Rewind tape */
#define MTOFFL 6 /* Rewind and take Offline */
#define MTNOP 7 /* No-Operation, set status only */
#define MTRETEN 8 /* Retension (completely wind and rewind) */
#define MTERASE 9 /* Erase the tape and rewind */
#define MTEOM 10 /* Position at End-Of-Media */
#define MTMODE 11 /* Select tape density */
#define MTBLKZ 12 /* Select tape block size */
/* Tape status: ioctl(fd, MTIOCGET, &struct mtget) */
struct mtget {
short mt_type; /* Type of tape device. */
/* Device dependent "registers". */
short mt_dsreg; /* Drive status register. */
short mt_erreg; /* Error register. */
/* Misc info. */
off_t mt_resid; /* Residual count. */
off_t mt_fileno; /* Current File Number. */
off_t mt_blkno; /* Current Block Number within file. */
off_t mt_blksize; /* Current block size. */
};
See mt(1) for a detailed description on what each operation does. The mt_type field is always zero, there is no use for it yet. Mt_dsreg
is 0 (OK), 1 (Error), or 2 (EOF encountered.) Mt_erreg holds the SCSI sense key of the last operation. Mt_blksize is the current tape
block size in bytes, zero if the block size is variable.
Note that one can issue these commands on a file descriptor that is in use to read or write data, something that mt can't do. So you can
add eof markers in the middle of an output stream, or get the status of a device before a rewind-on-close tape rewinds.
The driver will automatically add an end of file marker to a tape that is written to if you execute a space command. If you write eof
markers yourself then the driver will not add one extra on close.
